The 1858 is the first. Before it, Rolex's Perpetual rotor existed only in the 1931 patent filings and a handful of prototypes. After it, the Bubbleback dynasty runs for more than two decades and produces roughly 172 distinct reference variants: Cal. 520 giving way to 620 giving way to 630, Didactic engraved movements giving way to anonymous production watches, three-piece cases giving way to two-piece cases. The 1858 is where that lineage starts. It is also vanishingly rare at public auction: across more than twenty years of indexed records, only five ref 1858 lots have surfaced. | The 1858 is the first.
